Description
Technical field
Vehicle structure technical field is the utility model is related to, more particularly to a kind of lightweight automobile front longitudinal beam.
Background technology
Automotive safety is increasingly valued by the people, and front longitudinal is located at automotive front, is frontal crash of vehicles safe design
Crucial sensing unit, the energy accounting that front longitudinal absorbs in all car body components is more than 50%, therefore the suction of front longitudinal
Energy ability and deformation pattern determine the size of Path of Force Transfer and driving cabin intrusion volume in collision, and the design of traditional front longitudinal uses
The malformation that high strength steel plate D type form of fractures come during Collision-free, rule of thumb and result of the test, pass through that to adjust material thick
Meet crash requirements with material, if front longitudinal is thin, conquassation deformation pattern is undesirable, energy-absorbing deficiency, if front longitudinal is thick, holds
Easily front longitudinal is caused to occur bending and deformation；Therefore it is difficult to find equalization point, therefore this tradition in traditional front longitudinal design
Front longitudinal design can not coordinate to meet in collision safety design and low crash acceleration peak value and rational deformation conquassation pattern
Between balanced design.
And in existing automobile front longitudinal beam, section is not straight enough, bending weak spot be present, easily produce flexural deformation.When
Before when touching generation, bending weak spot can cause longeron to produce flexural deformation in advance, and the intrusion quantitative change of front panel is big when being touched before making, from
And cause the deformation of crew module to increase, cause occupant's living space to diminish, the injury to occupant can be caused to increase, because structure limits
System, front longitudinal inner section is not big enough, therefore section limited size system, can be vertical due to traditional front rail structure intensity deficiency
Increase reinforcing plate on beam inner panel and carry out reinforcement, therefore cause weight to increase, weight is big.
Utility model content
For this reason, it may be necessary to provide a kind of lightweight automobile front longitudinal beam, exist to solve automobile front longitudinal beam in currently available technology
Weak spot is bent, easily generation flexural deformation, front longitudinal inner section are not big enough, and section limited size and side rail increase are strengthened
The problem of plate weight increase.
To achieve the above object, inventor provide a kind of lightweight automobile front longitudinal beam, including upper beam and underbeam, it is described on
Beam and underbeam are hollow octagonal cylinder structure arranged in parallel, and are connected as a single entity by a side, upper beam and underbeam
From aluminum alloy material.
Prior art is different from, above-mentioned technical proposal has advantages below：By the way that front longitudinal is divided into upper beam and underbeam, on
Beam and underbeam are the octagonal cylinder structure be arrangeding in parallel, and are linked as upper beam and underbeam by a side of upper beam and underbeam
One, the column structure that a section is polygon being formed, column structure shape is straight, avoids appearance bending weak spot,
Flexural deformation is produced during shock in advance, polygonized structure adds the area of section of front longitudinal, improves structural strength, front longitudinal
Collision deformation pattern it is reasonable, reduce increased reinforcing plate on traditional front longitudinal girder inner plate, and use aluminum alloy material, reduce
The weight of front longitudinal (aluminium alloy density about in 2.55-2.85g/cm^3, and steel plate density is in 7.85g/cm^3 or so).
Further, it is provided with reinforcing plate in the hollow structure of upper beam and underbeam.
By setting reinforcing plate in the hollow structure of upper beam and underbeam, polygonal internal is divided into multiple independent carryings
Structure, increase the bearing capacity of polygonized structure.
Further, the rear and front end of upper beam and underbeam is provided with fixing hole.
By setting fixing hole in the rear and front end of upper beam and underbeam so that the upper beam and the lower ones structure is removable, is easy to preceding vertical
The energy-absorption box or front longitudinal of beam front end are changed in itself, avoid replacing front longitudinal from cutting and weld again, changing influences more
Change efficiency.
Further, it is filled with foamed aluminium in upper beam and underbeam.
By the filled and process aluminium in upper beam and underbeam, foam density low (for 0.1 to 0.4 times of metallic aluminium), absorb
Impact capacity is strong, light weight, increases the integral rigidity and impact resistance of front longitudinal, when colliding, can preferably absorb
Energy, reduce energy and be passed to driving cabin, so as to reduce the intrusion volume of driving cabin.
Further, the upper beam is provided with installing plate.
By setting installing plate on upper beam, it is easy to front longitudinal that crossbeam and damping tower are installed by installing plate.

Embodiment
To describe technology contents of the present utility model, construction feature, the objects and the effects in detail, below in conjunction with implementation
Mode simultaneously coordinates accompanying drawing to be explained in detail.
Also referring to Fig. 1, Fig. 2 and Fig. 3, Fig. 1 is the side view of lightweight automobile front longitudinal beam in the utility model embodiment
Figure, upper beam 101 and underbeam 201 are column structure, and are be arranged in parallel, and installing plate 102 is fixedly connected with (this implementation with upper beam 101
Installing plate is fixedly connected by way of CO2 welding with bearing beam in example), Fig. 2 is lightweight vapour in the utility model embodiment
The profile of Chinese herbaceous peony longeron, upper beam 101 and underbeam 201 are hollow eight-sided formation, the lower surface of upper beam 101 and underbeam 201
Upper surface be connected as a single entity (upper beam and underbeam are connected as a single entity by way of extrusion forming in the present embodiment), multi-disc reinforcing plate
301 are horizontally set in the hollow-core construction of upper beam 101 and underbeam 201, and both ends are connected with upper beam 101 and underbeam 201 respectively, foam
Aluminium 501 is arranged in the hollow-core construction of upper beam 101 and underbeam 201, referring to Fig. 3, fixing hole 401 is separately positioned on front longitudinal
Rear and front end, eight fixing holes are provided with per face, and (fixing hole is screwed hole in the present embodiment, and selects eight, the number of fixing hole
Amount can also be two or more).
According to said structure, in concrete operations, the rear end screwed hole of upper beam and underbeam passes through the fixtures such as bolt and car
Frame connects, the screwed hole installation energy-absorption box of front end, installing plate installation damping tower and crossbeam on upper beam, collision is received in front longitudinal
When, the energy-absorption box of front longitudinal front end installation first absorbs part energy, subsequent front longitudinal stress, the front longitudinal of increasing section area
Bigger energy is absorbed, the reinforcing plate being arranged in front longitudinal hollow-core construction makes to be divided into multiple independent stress knots in section
Structure, energy is absorbed respectively, foamed aluminium absorbs portion of energy simultaneously, and linear front longitudinal prevents part weakness stress area from shifting to an earlier date
Flexural deformation is produced, after an impact, it is only necessary to dismantle the i.e. replaceable energy-absorption box of bolt and front longitudinal of front longitudinal rear and front end.
Embodiment of the present utility model is the foregoing is only, not thereby limits scope of patent protection of the present utility model,
